WASHING AND BEATING ENGINE.

SPECIFICATION forming part of Letters Patent No. 672,170. dated April 16. 1901.

Application iled December 1, 1900. Serial No. 38,291` lN0 model-l To all whom it may concern-.-

Be it known that I, ROBERT J. KISSOCK, residing at Boston, in the county of Suolk and State of Massachusetts, have invented certain Improvements in Washing and yBeating Engines,of which the following is aspecification.

This invention relates to washing and beating engines employed in paper-making; and it consists in improvements in such engines by means of which the work of washing and of beating the stuff is greatly facilitated.

Of the drawings which illustrate the invention, Figures l and 2 are respectively a plan and a sectional View of such an engine embodying my improvements, and Fig. 3 is a modification of the invention.

a represents the tub of a washing or beating engine, which may be twenty feet long, seven feet wide, and three feet high, having rounded corners.

b is a shaft supported in bearings d and e and provided at its outside end with a pulley, by means of which power is applied thereto, and upon the shaft, between the bearings, is a roller f, having longitudinal knives h, secured in its periphery. The roller is adapted to be raised or lowered by suitable means and revolves in the direction of the arrow in the operating passage-way s2.

n is the inlet to the roller, and that part of the oor of the tub of the width of the roller is inclined toward the roller, and back of the same it sweeps up in a curve and then falls away to the ordinary floor-level, and directly under the roller are secured the teeth m, which extend across the tub parallel with the knives in the roller and coperate therewith to abrade and rub the stu and toward which the latter knives are adapted to be regulated.

In Figs. 1 and 2 the roller is represented as midway of the sides of the tub, and there is a mid-feather g on each side thereof, dividing the tub into the central operating passageway s2 and the two side passage-wayss s, and when the roller is in motion the stui, after passing under the roller and down the backfall 1o, when it reaches the end of the tub r divides and one-half thereof passes down each side passage s s and meets at the inlet fn. of the operating passage-way to undergo the same operation again.

The foregoing description relates to what is old and well known in the engines for the purposes set forth, in the operation of which I have found a serious difficulty. In all such engines that I am aware of the approach or inlet-space to the roller is arranged as shown in Fig. I that is to say, there are two walls gzextendingoutward at right angles to the axis of the roller, forming the inclosed space or inlet/mand during the rotation of the rollerin the stuff, some of which is brought over the top of the roller by the knives h, the stuff becomes packed in front of the same and especially at the right-angled corners B between the walls g2 and the face of the roller, and the stu remains in a dead state there and blocks the passage to the roller, so much so that the circulation of the stuff becomes very slow,and a man has frequently to assist the circulation with a paddle. A

My improvement consists in gradually narrowing the inlet-space n from the entrance toward the roller horizontally, as shown in Fig. 2, and I find that by so doing the former dead-corners are eliminated and that when the roller is Arevolving the stuff is carried along under the roller with comparatively great rapidity. For instance, I find that in operating the ordinary engine without my improvement attached the stuff completes the cycle from the roller over the backfall to the inlet and roller again in about sixty seconds, but in thel same engine provided with a narrowing inlet, as shown in Figs. 1 and 2, the cycle is completed in eighteen seconds.

The means by which the inlet-passage n is narrowed may be widely varied without departing from the spirit of the invention. When such engines are made in standard sizes, the correct angle for the inlet can be and is determined by experiment for any certain kind of stuff, and the means may be simply a solid angle-block A properly secured to the walls g2 at each end of the roller, as shown in Fig. 2. In some cases, however, it

may be desirable to make the angle-piece adjustable, so that the angle of the inlet may be varied, as shown in Fig. 4, in which 7l is a wing pivoted at one edge by a hinge 2 to the wall g2 and having Secured at its free end a flange 3, which is adapted to slide upon the IOO face of a projection 4 from the walls g2. 5 is a bolt passing through the Wing into a nut '7 in the Wall g2, and 6 is a set-nut ou the bolt to prevent the wing e' from closing up, and the head of the bolt prevents the wing from swinging out.

I nd in adjusting the angle-piece A that the operation of the engine is more favorable-that is, the stuif passes to the best advantage when the inner end of the said piece is inside the end of the knives h or toward the center of the passage-way, and also that better results are obtained when the anglepiece is made so that none of the stud can get inside or behind it, and thus create a dead space.

I claim as my inventionl. A Washingor beatingengine for the purpose set forth, consisting of a tub, one or more mid-feathers in said tub dividing the same longitudinally to form two or more passage-Ways, a shaft provided with rotating` means, suitable bearings for said shaft, a roller carried by said shaft, knives on said roller, which coincide with stationary teeth secured in the bottom of the tub, the said roller being located in the operating passageway and at right angles to the same, with means for horizontally narrowing the passage-Way from its entrance toward the roller.

2. Awashing or beating engine for the purpose set forth, consisting of a tub, one or more mid-feathers in said tub dividing the same longitudinally to form two or more passage-Ways, a shaft provided with rotating means, knives on said roller which coincide With stationary teeth secured in the bottom of the tub, the said roller being located in the operating passage-wayand at right angles to the same, with adjustable lneans for horizontally narrowing the passage-way from 'its entrance toward the roller.

3. A washing or beating engine for the purpose set forth, consisting of a tub, one or more mid-feathers in said tub dividing the same longitudinally to form two or more passage-ways, a shaft provided with rotating means, suitable bearings for said shaft, a roller carried by said shaft, knives on said roller adapted to coincide with coperating or rubbing stationary teeth in the bottom of the tub, the said roller being located in the operating passage-Way and across the same, with means for horizontally narrowing the passage-way from its entrance toward the roller.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, this 30th day of November, 1900.
